When a minor character in a film or tv series with little screen time becomes one of the most beloved characters in the show/movie. Its name originates from the character Boba Fett from Star Wars who, despite having little screen time, very few lines and a disappointingly lame death in the original trilogy, gained a cult following and is by far one of the coolest characters in the Star Wars universe.
